In anguish: Tears ran down the cheeks of a man as he waited with other survivors Tuesday for a flight out of Tacloban in the Philippines, which was devastated by Typhoon Haiyan.

As some trucks loaded with food and other aid arrive in the Philippine city of Tacloban, they're being looted by residents struggling to survive in the aftermath of Typhoon Haiyan, NPR's Anthony Kuhn said Wednesday on Morning Edition.

He's spoken with many of those people, and they seem to be "ordinary folks who would not do such things in ordinary times," Anthony told host Steve Inskeep. "But they are doing such things to stay alive."

In Tacloban, he added, a fight for "sheer survival" is under way as people in the city of more than 220,000 search for food, water and other essentials. As of Wednesday, there weren't enough government troops in the area to control things.

"TACLOBAN, the Philippines — The mayor of this typhoon-ravaged city urged residents on Wednesday afternoon to flee to other cities and find shelter there with relatives if they could, saying that the local authorities were struggling to provide enough food and water and faced difficulties in maintaining law and order."

While the government, international aid groups and foreign militaries that have rushed to the affected area are having trouble getting to the victims because of blocked roads, the U.S. commander on the scene told NPR early Wednesday that American assistance has quickly ramped up.

Marine Brig. Gen. Paul Kennedy said that "this disaster is five days old for the people of the Philippines, [but] we've effectively only had U.S. military operations for the last 72 hours. And in 72 hours, we've gone from essentially a cold start — I flew in here with six people and a suitcase staff — to running ... aircraft. We moved 65 tons of humanitarian assistance supplies yesterday. That's a lot of stuff. We'll do the same today."

Brig Gen. Paul Kennedy, the on-site commander of U.S. military relief operations in the Philippines, says the airfield at hard-hit Tacloban City is now "24/7 capable."

A statement from U.S. Marine Corps Forces, Pacific, says:

"The U.S. military has conducted approximately 40 flights in support of Operation DAMAYAN ('Help in Time of Need' in Tagalog), inserting more than 400 relief workers from USAID, its Office of U.S. Foreign Disaster Assistance (OFDA), and nongovernment organizations. The joint relief efforts have also airlifted more than 800 displaced people.

Over the next 24 hours, 3d MEB is preparing to receive approximately 180,000 pounds of USAID relief supplies, including plastic sheeting, hygiene kits, food and water, which will be distributed to areas in need."

Gen. Kennedy tells NPR that the Marines have been using C-130s to get supplies into Tacloban, but roads are still blocked from the airport to outlying areas that need help.

"The bridges thankfully are still intact," he says. "Once those roads are cleared, we'll be able to start moving out of the airport."
